First of all, thanks for your help, for your quick reply.
Secondly - about the building
It is located on main stress - nearly shopping center as Big C, Platinum mall, ...
Staff is very helpful (except can not speak englisg)
Thirdly - suggestions
1. Bangkok lives 24h/24h, they need to improve sound - proof system. It’s hard to sleep.
2. AC system should be set up above the window. We slept on mezzanine, we felt it was not cool
3. Water pressure is low
4. Should take a staff to guest’s room to clean or collect garbage daily
5. It will be better if you may prepare for guest some brochure as city map, famous destination maps
Overall, we have great time at Bangkok, thanks for everything
